What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Barrington borough, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Properties in Barrington borough, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally.

Preparing for a Blower Door Test in Barrington borough, NJ

To prepare a home for blower door test in Barrington borough, NJ, we shut off the HVAC system and disable all exhaust fans. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Barrington borough, NJ efficiency standards.
